Firmware 1.2.5.3 Last Updated: 03/2011

Welcome

Your Grandstream GXP Series IP phone features a new sophisticated design and is very easy to use.

The GXP combines advanced feature functionality with the latest technology to offer excellent audio

quality, ease of use, expandability, and broad interoperability with 3

rd

party SIP platforms. It is ideal for

the enterprise customer.

The GXP Series supports a broad range of codecs, security protection, PoE (not supported on GXP-280),

dual 10/100mbps Ethernet ports and are very easy to manage. Currently, the GXP Series consists of the

following six models: GXP-280, GXP-285, GXP-1200, GXP-2000, GXP-2010 and GXP-2020. Each model

delivers superior audio quality using either a handset, hands-free speakerphone or headset (except for

GXP2000) and supports multi-party conferencing, multi-languages, dual-color LEDs, presence and BLF

(on most models). Large easy-to-read backlit graphical displays with multiple XML keys further enhance

the user experience (not supported on GXP-280/285). Some models (GXP-2000, GXP2010 and

GXP2020 currently) are expandable with one or two expansion module.

The series is based on SIP standard and are interoperable with most 3rd party SIP platforms and open-

source platforms.

Caution: Changes or modifications to this product not expressly approved by Grandstream, or operation

of this product in any way other than as detailed by this User Manual, could void your manufacturer

warranty.

Warning: Please do not use a different power adaptor with the GXP as it may cause damage to the

products and void the manufacturer warranty.

Connect the first GXP –EXT to the GXP–2000 using the PS2 cable found in the GXP Extension package.

The first GXP–Ext draws power directly from the phone. Connect the second GXP Extension unit using the

connection plate and the PS2 cable. The GXP2000 will automatically reboot and power up the GXP

Extensions. Grandstream recommends, though not required, to use a separate power supply with the

second GXP Ext.

NOTE: should your system lose power, please unplug your devices and power up the GXP–2000 first.

Powering up the system:

1. The GXP–2000 will boot up first;

2. The GXP LEDs will be solid red;

3. The status light in the top right corner of the GXP–Ext will blink red;

4. All of the LED indicators on the GXP–Ext will flash three times;

5. The status light at the top right corner of the GXP–Ext will turn to solid green.

NOTE: 1. Extension for GXP2010 and GXP2020 does not support hot-swap. Once connected, user should

reboot the phone to ensure the set up will work correctly.

2. GXP2010/GXP2020 can drive 2 extension modules. Independent power adapters are not needed

for extension modules.

MAKING PHONE CALLS

Handset, Speakerphone and Headset Mode

The GXP series phones allow you make phone calls via handset, speakerphone, or headset mode. During

the active calls the user can switch between the handset and the speaker by pressing the speaker key. For

headsets to operate, the user must plug the headset to an RJ22 or 2.5mm port on the phone, which allows

the user to pick-up, speak, or hang-up calls.

Multiple SIP Accounts and Lines

GXP can support up to six independent SIP accounts depending on the product model. Each account is

capable of independent SIP server, user and NAT settings. Each of the line buttons is “virtually” mapped to

an individual SIP account. The name of each account is conveniently printed next to its corresponding

button. In off-hook state, select an idle line and the name of the account (as configured in the web interface)

is displayed on the LCD and a dial tone is heard.

For example: Configure ACCOUNT 1 and ACCOUNT 2 with Account Name as “VoIP 1”, “VoIP 2”,

respectively and ensure that they are active and registered. When LINE1 is pressed, you will hear a dial

tone and see “VoIP 1” on the LCD display; when LINE2 is pressed, you will hear a dial tone and see “VoIP 2”

on the LCD display.

To make a call, select the line you wish to use. The corresponding LINE LED will light up in green. User can

switch lines before dialing any number by pressing the same LINE button one or more times. If you continue

to press a LINE button, the selected account will circulate among the registered accounts.

For example: when LINE1 is pressed, the LCD displays “VoIP 1”; If LINE1 is pressed twice, the LCD

displays “VoIP 2” and the subsequent call will be made through SIP account 2.

Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the

“virtually” mapped line is in use, the GXP will flash the next available LINE (from left to right or from top to

bottom for Multi Purpose Keys) in red. A line is ACTIVE when it is in use and the corresponding LED is red.

Making Calls using IP Addresses

Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls

can be made between two phones if:

• Both phones have public IP addresses, or

• Both phones are on a same LAN/VPN using private or public IP addresses, or

• Both phones can be connected through a router using public or private IP addresses (with necessary

port forwarding or DMZ)

To make a direct IP call, please follow these steps:

1. Press MENU button to bring up MAIN MENU.

2. Select “Direct IP Call” using the arrow-keys.

3. Press OK to select.

4. Input the 12-digit target IP address. (Please see example below).

5. Press OK key to initiate call.

To make a quick IP call, please see next section.

For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input

the following: 192*168*1*60#5062 - The “ * ” key represent the dot“.” ; The “#” key represent colon “:”.

Press OK to dial out.

Quick IP Call Mode

The GXP also supports Quick IP call mode. This enables the phone to make direct IP-calls, using only the

last few digits (last octet) of the target phone’s IP-number.

This is possible only if both phones are in under the same LAN/VPN. This simulates a PBX function using

the CMSA/CD without a SIP server. Controlled static IP usage is recommended.

Setting up the phone to make Quick IP calls

To enable Quick IP calls, the phone has to be setup first. This is done through the web-setup function. In the

“Advanced Settings” page, set the "Use Quick IP-call mode to YES. When #xxx is dialed, where x is 0-9 and

xxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. “aaa.bbb.ccc” is from the local IP address

regardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but OK).

For example:

192.168.0.2 calling 192.168.0.3 -- dial #3 follow by SEND or #

192.168.0.2 calling 192.168.0.23 -- dial #23 follow by SEND or #

192.168.0.2 calling 192.168.0.123 -- dial #123 follow by SEND or #

192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3

NOTE: If you have a SIP Server configured, a Direct IP-IP still works. If you are using STUN, the Direct IP-

IP call will also use STUN. Configure the “Use Random Port” to “NO” when completing Direct IP calls.
